I was shocked when I calculated β a salted egg has about 80-90 calories versus 60-70 for a boiled egg. The real issue isn't calories, it's sodium. A salted egg packs about 600-800mg of sodium β roughly a third of your daily intake.
But if you're craving a salted egg so badly you're about to fall off your diet β eat it. The psychological benefit outweighs 20 extra calories and the sodium. Just account for it in the rest of your day. Drink more water. Eat lower sodium meals.
The idea that dieting has to be miserable is why so many people give up. One salted egg won't ruin your progress. Don't make it a daily habit, but if you're staring at another boiled egg with tears in your eyes, swap in a salted egg once or twice a week. Your sanity matters more than a hundred calories.
